Description

ELECTRONIC DEVICE AND METHOD FOR PROVIDING 3D IMAGE } One or more embodiments of the present disclosure relate to electronic devices, for example, to an electronic device that renders and provides a 3D image and a method for providing a 3D image. The purpose of display technology is to convey natural three-dimensional space or virtual spatial information unfolding before the eyes to humans more accurately and realistically. To create natural and immersive images that make one feel as if they are actually in that place, 3D stereoscopic video technology is being developed in various ways. 3D display technology includes glasses-based and glasses-free types, and encompasses stereoscopic 3D displays (e.g., glasses-based, two-viewpoint), multi-viewpoint, and holographic 3D display technologies. Due to the discomfort caused by wearing 3D glasses, glasses-free technology is being researched. Conventional stereoscopic 3D displays contain two viewpoint image information points for viewing stereoscopic images. Due to limitations in the field of view, the viewpoint changes discontinuously, leading to problems such as unnatural motion parallax and focus-convergence mismatch, which cause eye strain and dizziness. A viewpoint image refers to the image seen when a user looks at a 3D display in actual physical space. To address these two issues, various methods to secure a wider field of view are being researched. From a hardware perspective, research is being conducted on multi-viewpoint methods that can provide more natural 3D effects by attempting to increase the number of viewpoints. From a software perspective, rendering methods are being researched that track the user's position and provide optimal 3D stereoscopic images based on that position by rearranging pixels appropriate to that location. The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art related to the present disclosure.
